“ Forests of the Rocky Mountains,’towards the sources of the Oregon.—
Stem tall, sparingly clothed on the lower part with forked hairs. Radical
leaves not seen; cauline ones about 2-inches long, sessile or clasping. Flowers
purple; petals longer than the sepals, linear-oblong.” Nutt.
12. A. puberula (Nutt, mss.): “ perennial, somewhat csespitose, more
or less pubescent with dense stellate hairs ; leaves entire, linear-lanceolate,
sessile ; siliques flat, straight, pendulous, the pedicels about twice the length
of the sepals ; seeds with a slight margin.
“ Forests of the Blue Mountains of Oregon.—Stem about a span high.
Flowers not seen. Siliques slightly pubescent, the central nerve obvious.”
Nutt.
13. A. microphylla (Nutt, mss.) : “ smoothish and somewhat csespitose;
leaves linear, rather acute ; cauline ones very few, sessile : stem filiform,
very few-flowered ; silique long, flat, spreading.
“ Rocky Mountains: rather rare.—Leaves scarcely half an inch long.
Siliques only 2-3, at the summit of the filiform stem, 24 inches long. Flowers
small, pale purple.—A smaller and fewer-flowered species than the preceding.”
Nutt.
** Seeds with a broad winged margin.
14. A. lavigata (D C .): erect, whole plant glabrous and glaucous; radical
leaves oblong-obovate, attenuated into a petiole at the base, or somewhat
sessile, acutely dentate-serrate ; cauline leaves sessile; the lower ones lanceolate,
sagittate, sparingly toothed; uppermost linear, entire; flowers spreading;
siliques linear, narrow and elongated, recurved-pendulous.—D C. ! syst.

Rocky woods, and along rivers, Canada! to Virginia; west to Missouri

purplish color; cauline ones 2-6 inches long, acutely toothed (the teeth in
/?. long and narrow). Sepals greenish-yellow, nearly as long as the narrow
cuneiform erect (white) petals. Siliques 2-3 inches long and less than a
line in breadth, pointed with the very short style. Funiculi adhering to
the septum at the base.—Willd enow erroneously states that the siliques are
erect, which mistake has led to much confusion respecting our plant. The
description of De Candolle was drawn from a dwarf specimen, without fruit
in Pursh’s herbarium.—T. laevigata, Hook, fl, Bor-Am. l. p. 43, must be a
very different plant from the one here described.
15. A. Canadensis (Linn.): erect; leaves oblong-lanceolate, sessile, attenuate

Rocky places, Canada ! to Georgia! west to Arkansas! June-July.—
Stem 2-3 feet high, simple, glabrous, pubescent below. Leaves 2-4 inches
long, nearly glabrous, or pubescent with simple hairs, rarely villous; the
lower ones attenuated into a petiole, and sometimes lyrate or runcinate. Racemes
elongated. Pedicels spreading recurved in fruit, sometimes hispid.
Sepals yellowish, hispid. Petals white, oblong-linear, twice as lon°- as the
calyx, nearly erect. Siliques 2-3 inches long, 14 line wide, ancipital. Funiculi
adhering to the septum, as was first noticed by R. Brown. ( PI. o f Oud-
ney, &c. p. 11.)
